Not to mention that eBay puts listing limits on new sellers; you may not be able to list 100 items, not to mention 400 until you build up your FB

I went through that for months and it was hard for me even when i was at 260 for my limit. Once that got raised twice since then, I find it much easier and sales have boomed. I have a selling structure that seems to be working well for me and I am still way off my limit.I am still small compared to most other fellow PowerSellers, but my signs look good

eBay will expect the OP to stick with the selling limit for a whole month before another selling limit increase will be considered
